Biophysical Technologies for Debridement: Comparing and Contrasting Pulsed Lavage and Contact Low-Frequency Ultrasound


Dr. Stephanie Woelfel is an Assistant Professor of Clinical Physical Therapy and Surgery at the University of Southern California (USC) in Los Angeles, California. She is the Director of Clinical Physical Therapy for Hospital Outpatient at Keck Medical Center of USC, where she treats patients with various wound diagnoses and participates in clinical research. She is also the primary physical therapist in the Southwestern Academic Limb Salvage Alliance (SALSA) of USC. Her wound care career has spanned over 20 years in both short- and long-term acute care, skilled nursing facilities, home care, and consulting. Stephanie is active in the American Physical Therapy Association (APTA) and is the current President of the APTA’s Academy of Clinical Electrophysiology & Wound Management. She also represents the APTA on the National Pressure Injury Advisory Panel.

Pulsed lavage (PL) is a form of mechanical hydrotherapy that applies topical solutions under pressure to irrigate and debride wounds, with or without the concurrent application of suction. Closed pulse irrigation and PL with suction are two examples that will be discussed. Contact low-frequency ultrasound uses an irrigation medium to deliver ultrasound energy to the wound bed for immediate debridement of necrotic tissue. This session will highlight PL and contact low-frequency ultrasound, key components to consider when choosing one of these biophysical agents, and will compare and contrast both technologies.
